   Summary

   A new trainer has arrived at Tracen Academy, like he expected he meets all kinds of Umamusume but one piqued his interest more than the others, Agnes Tachyon, this complete novice of a trainer doesn’t believe he can trainer a talent like Agnes, little does he know when they met she wanted to experiment with him with him as her trainer (or something like that I may change this later I wasn’t planning on putting this on here)
